Has anyone ever had issues with ip address reservations in DHCP not working at all?   It works fine for Windows servers but the Ubuntu servers will get an ip but not the correct ip they should get.  MAC addresses are all correct in the reservation, they match up with what's on the client screen, but the Ubuntu server will just get whatever ip is available on that vlan.   This has been an issue since putting in the Cisco 9300X-24X-HM stack.  We have the same issue whether the dhcp is being done by the stack or by the MX85s, DHCP works fine apart from the reservations for the Ubuntu servers.   Meraki/Cisco support is looking at other issues with the 9300X stack, presume this is all related to that. ...

Have a bonded pair of 10GbE ports on a Ubuntu server, bonded in the Round Robin mode, plugged into 2 stacked C9300X switches.  There is an alert constantly coming up about MAC address flapping.   Aggregating the 2 ports on the switches causes both ports to get blocked.  Anyone who knows Ubuntu/Linux know what the bonding mode should be please?   The Windows servers are working fine with Switch Independent SET configured. ...

Hi everyone, we've got 2 WAN links to the internet at our main site.  WAN 1 is a 200Mb link and WAN 2 is a 50Mb link.  This is all configured through a Cisco Meraki MX and MS network. All of the Cisco phones were migrated today from CUCM to Webex Calling, all the phones are on a vlan of 1200 and in Flow Preferences within SDWAN & Traffic Shaping on Meraki, i've setup internet traffic for that VLAN to go out through WAN 2, so source is 10.1.200.0/24 with any port and any destination.  I've also setup a rule that says any traffic going in to that vlan goes through WAN 2 as well, i've also added additional rules for any UDP traffic with a source port of 9000-9009 and 5060-5070 will go through WAN 2 when it comes from any vlan. The issue seems to be though that in Cisco Webex Calling management, when looking at the analytics, some of the public ip addresses for calls is the WAN1 public ip and some are WAN2 public ip.  All the handsets are set up the exact same way so not sure why there is a difference.  Anyone have any ideas why?  We do have Webex Windows client on the client machines and all traffic that doesn't match the above rules go through WAN1. The issues we're having is WAN1 tends to be saturated with client and server traffic and WAN2 was gotten purely to be for any VoIP and Webex traffic. ... View more

Installing 2 C9300X-Ms this coming weekend. I know i require 2 data stacking cables, going from stacking port 1 to port 2 on both switches.  Never stacked power before though and i can't find if i need 2 power stacking cables as well or if a single power stacking cable is fine?   ... View more

Looking on the C9300X-M datasheet site on the Meraki website, it lists the optional accessories at the bottom of the page.  The Cisco page lists more items, in particular the C9300X-NM-8M, which isn't listed on the Meraki page, is every module on the Cisco page also compatible with the Meraki firmware?   Catalyst 9300X-M Datasheet - Cisco Meraki Documentation   Cisco Catalyst 9300 Series Switches Data Sheet - Cisco   I'm asking as it'll be plugging into an MX85 and ideally wanted to stick with 10GbE rather than SFP+ or SFP28 and optical cabling.   If not, i'll ask the Meraki support to clarify. ...

Can't find the answer anywhere, i know the Cisco 9300s need the Meraki firmware installing out the box to get it managed by the Meraki dashboard but if it's the Meraki 9300X-M, does that mean it's already got the Meraki firmware or will it still need flashing out the box?     ... View more

Our licenses for our networks are running out in a few months time so just costing up for another 5 year renewal.  All of our kit is running fine, it's all happy, never had issues so thought the cheapest option was to just license again and go.  However, the quote's we're getting back from 1 of our suppliers doesn't make sense unless Meraki are penalising us for sticking with old EOL kit.   As an example, hiding the exact costs, but.   1x MX100 Advanced Security license for 5 years (license only) = £12500. 1x MX85 + Advanced Security license for 5 years (license and hardware) = £6700   Looking at the spec differences between the MX85 and the old MX100, the MX85 is better in pretty much everything.   We've got some old MX64s as well around the business, upgrading them to MX67s, which we don't need to do, and adding a 5 year advanced security license is around £35 more expensive than just a license for the MX64.     ...

HI everyone, i've had a look around and googled and gone through guides and i can't seem to find the answer anywhere.   Our main site has 2 WAN connections now, a 200Mb link that most data uses, including all SDWAN traffic to the other sites that we have and VPN traffic from client VPNs coming in and also general internet and office usage.  The 2nd link is 50Mb and i set an SD-WAN policy in the "SD-WAN & Traffic Shaping" screen to put all VoIP and Video Conferencing traffic to prefer WAN2 with failing over if poor performance. Now how do i confirm that is exactly what is happening, i'd love to be able to go into Traffic Analytics for WAN appliances, click the MS Teams Video application and for it to show me which WAN interface that traffic used but i can't.  I have done a packet capture for the "internet 2" interface and all the traffic is UDP traffic of between 87 and 236 bytes, meaning it does look like VoIP traffic, but i'd ideally like a clearer picture if possible? ...

Looking at upgrading our little Datacenter network and servers to 10Gb, currently have 2 Meraki switches in there that are happily running off of 1Gb but Meraki doesn't seem to do any 10Gb switches with anything close to enough 10Gb ports to meet our requirements, unless we look at the MS390 switches, we generally use the 1xx and 2xx series switches round the network.   We need at least 8x10Gb and the best option for us seems to be to add a non-Meraki switch, something like a Netgear XS708Ev2 and essentially have 2 networks with the servers prioritising the 10Gb link and then failing over to the 1Gb Meraki switches if the 10Gb link goes down but it's not ideal. ...

HI everyone, got an SDWAN configured across all of our sites running Meraki kit and all running at least 18.107.2, including the site with an issue.   We have 2 MX84s, 1 configured as primary and 1 as the hot spare.  If we make a change to the DHCP settings on the MX, the connection to the internet stays up but the SDWAN will drop for about 10 seconds every time.   Anyone seen this before?     ...
